A TTORNE Y HARRY D. BOWMAN, OF EAST ORANGE, NEW JERSEY.

PROCESS OF FILLING FUSE-CONTAINERS FOR POWDER-BAGS.

Specification of Letters Patent.

Patented Mar. 25, 1919.

Application filed February 13, 1918. Serial No. 216,993.

To all whom it may concern:

Be it known that I, HARRY D. BOWMAN, a citizen of the United States, residing in the city of East Orange, county of Essex,

and State of New Jersey, have invented a new and useful Improvement in Processes of Filling Fuse- Containers for Powder- Bags, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, forming a part of this specification.

The invention has relation to a process of filling the fabric fuse containers of powder bags with an explosive compound. The container comprises a central and end members which are made from porous material so constructed as to provide powder receiving pockets or elements designed to receive the black powder which when ignited sets fire to the smokeless powder contained in the powder bag of which the central and end members of the fuse container forms a art.

Hitherto it has been customary to fill the said containers by hand, preferably employing a stick or the like to force "the powder into the powder receiving pockets or elements thereof, the operation being a tedious and unsatisfactory one.

The distinctive novelty of the process consists in forcing air under pressure into the powder receiving pockets or elements of the 'fuse container thereby distending the same and simultaneously introducing an explosive compound, such as black powder, into said current of air whereby the explosive compound is forced into said powder receiving pockets or elements of the container while the air is permitted to escape through the fabric of the powder pockets of the said container.

The process I perform in the preferred embodiments of my invention, which I have illustrated in the accompanying drawings, having it understood that I am not limited to the specific details of construction shown and described, as it is manifest that these may be modified and changed without depar-ting from the spirit or scope of the invention.

In the accompanying drawings,

Figure 1 represents a side elevation, partly in section, of a powder bag provided with a fuse container.

Fig. 2 represents an end elevation, and

Fig; 3 represents a side elevation partly in section of the mechanical appliances employed for filling the fuse containers.

Similar characters of reference refer to like parts throughoutthe specification and drawings.

In describing the process of my invention, I will simultaneously describe the mechanical appliances employed, so that those skilled in the art to which it pertains, may gain a full knowledge of the appliance as well as the process.

In the drawing, 1 represents a powder bag of ordinary construction, filled with smokeless powder and 'having centrally located therein the central member 2 of the fuse container which has attached thereto, what are known as, end or detonating members 33 which members constitute a part of each end of the powder bag and which are secured thereto by means of stitching. The central member 2 and end or detonating members 3-3 are made of porous material and are provided with powder receiving pockets or elements 4 for the reception of the black powder or other explosive compound 5 and which may be of any desired form or configuration. The powder receiving elements or pockets are formed by stitching the layers of the porous fabric of which the fuse container is made together.

The mechanical appliance employed for filling the fuse container consists of a suitable source of air supply derived from the air supply pipe 6, which pipe communicates with the open or discharge end 7 of the powder chamber or container 8, as clearly indicated in the drawings. The powder container 8 is provided with a closed end consisting of a screw cap 9 having a vent 10. The operation of the device and the process of filling the fuse container is as follows:

The end of the pipe 6 at 11 is inserted in an opening 12 formed in the central member tainerffandj'si nultaneously introduces "the- V granular explosive compound which is con r tamed 1n the powder chamber or conta ner "8' into said, pockets tin-such" a inanfierfthat the GXPlOSlVG compound is arrested .by the meshes f the "fabric ofthepovvder ""ockets hile the air is permitted to escape t rough are-wbemdmen sthe otherhalfvof the-'gfuse 1.
